PROFIBUS DP (MK2) OPTION CARD PROPERTIES
2.1 Mechanical properties
The PFU module consists of a network interface card, that either fits directly to the main actuator
printed circuit board (CVA and ROMPAK) or fits to an interface card; then the two board assembly is
fitted inside the actuator electrical housing (IQ range, Skil/EH and Q).
All the connectors are polarised to prevent incorrect insertion.
Network Interface Card (NIC)
This small printed circuit board carries the Profibus DP, RS485 highway connections and
protection circuits.
There are two versions of the Network Interface Card, one for a single highway and a second
for two highways, Simple or RedCom Dual. (RedCom has two highway configurations, two
highways for SR mode or one highway with two network interface connections for FR use.)
